Hightlights include:
Stable bugfixes:
- Fix mirror allocation in the writeback code to avoid a use after free
- Fix the O_DSYNC writes to use the correct byte range
- Fix 2 use after free issues in the I/O code
Features:
- Writeback fixes to split up the inode->i_lock in order to reduce contention
- RPC client receive fixes to reduce the amount of time the
xprt->transport_lock is held when receiving data from a socket into am
XDR buffer.
- Ditto fixes to reduce contention between call side users of the rdma
rb_lock, and its use in rpcrdma_reply_handler.
- Re-arrange rdma stats to reduce false cacheline sharing.
- Various rdma cleanups and optimisations.
- Refactor the NFSv4.1 exchange id code and clean up the code.
- Const-ify all instances of struct rpc_xprt_ops
Bugfixes:
- Fix the NFSv2 'sec=' mount option.
- NFSv4.1: don't use machine credentials for CLOSE when using 'sec=sys'
- Fix the NFSv3 GRANT callback when the port changes on the server.
- Fix livelock issues with COMMIT
- NFSv4: Use correct inode in _nfs4_opendata_to_nfs4_state() when doing
and NFSv4.1 open by filehandle.
